It accepts 100 to 240 VAC, 50/60 Hz, with a voltage fluctuation tolerance of 85% to 110% of rated supply. Power consumption runs about 9.4 VA at 100-240 VAC, or 7.2 VA / 4.7 W on 24 VAC or 12-24 VDC supply variants. Counting speed is switchable between 30 Hz and 10 kHz, with a 1:1 ON/OFF ratio. That 10 kHz rate handles fast-cycling parts on a pick-and-place or a high-speed packaging line; the 30 Hz position filters contact bounce on mechanical switches or relay outputs. Input mode is selectable for increment or decrement, so it works for both totalizing and countdown applications. ## Output modes and timing Output modes include N, F, C, R, K-1, P, Q, and A — these cover self-holding, one-shot, and batch-counting patterns common in batching or cut-to-length machines. One-shot output time is adjustable from 0.01 to 99.99 seconds, which lets you tailor the pulse width to a PLC input scan or a solenoid valve response. Reset can be external (minimum signal width selectable between 1 ms or 20 ms), manual, or automatic. The 1 ms setting works with fast PLC outputs; the 20 ms setting debounces a mechanical pushbutton. A prescaling function from 0.001 to 99.999 lets you scale encoder pulses to engineering units — useful for linear measurement with a rotary encoder. Mounts flush or surface on a panel. External connections go through an 8-pin socket, so wiring is a plug-in affair — swap the counter without pulling wires. Sensor waiting time is 290 ms max, which matters if you're cycling power to the counter between batches; the count input won't miss the first pulse after power-up. ## Environmental limits Operating humidity range is 25% to 85%.","metaTitle":"Omron H7CZ-L8 Digital Counter, 1-Stage Preset, 100-240 VAC","metaDescription":"Omron H7CZ-L8 1-stage preset digital counter.
